chore: global changelog logic to work before changeset version

[caseyisonit]

Description

This command has to run before changeset version, so we need to manually figure out the correct nextVersion for the changelog and URLs.

Motivation and context

This ensures our changeset will match the correct/same version when changeset version is run in changeset publish

Review the following VRT differences

When a visual regression test fails (or has previously failed while working on this branch), its results can be found in the following URLs:

• Spectrum | Light | Medium | LTR
• Spectrum | Dark | Large | RTL
• Express | Light | Medium | LTR
• Express | Dark | Large | RTL
• Spectrum-two | Light | Medium | LTR
• Spectrum-two | Dark | Large | RTL
• High Contrast Mode | Medium | LTR

If the changes are expected, update the current_golden_images_cache hash in the circleci config to accept the new images. Instructions are included in that file.
If the changes are unexpected, you can investigate the cause of the differences and update the code accordingly.
